Specification of Letters Patent.

Patented May 6, 1212..

Application filed December 29, 1917. Serial No. 209,412.

To all whom it may concern:

Be it known that l, Gannon HILLARD BEN- JAMIN, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Ev'aporators, of which the following is a specification.

My invention relates to evaporators of the type used for evaporating salt water to obtain approximately freshwater and salt.

The object of my invention is a construction, whereby:

(1) The evaporator coils and manifolds are not attached to or supported by the door of the evaporator as is usual, but may be readily introduced into and removed from the evaporator shell.

(2) The steam connections to the shell of the evaporator are permanent, and are not broken when the evaporator coils and mani folds are removed from the shell.

(3) The union between the steam connections and th manifolds is efiected from outside of the evaporator shell.

(4:) Means are provided for swinging the door away from the evaporator shell and the manifolds and evaporator coils out of the shell, independently of each other.

The accompanying drawin s will serve to illustrate my invention, in w ich:

Figure 1 is a front elevation with a part broken away to show the evaporator coils.

Fig. 2 is a vertical section taken on the line HII of F ig. 1.

Fig. 3 is a horizontal section taken on the line III-III of Fig. 2.

Fig. 4: is a horizontal section corresponding to Fig. 3 and showing the door in the open position, and the manifolds and coils in full lines in position as they are moved out of the shell, and in dotted lines, when wholly out of the shell.

In the drawings, 5 represents the shell, which may be of any suitable material. 6 indicates a pipe, through which salt water maybe introduced into the shell, and 7 a waste water or wash out pipe. These pipes are provided with suitable valves. Connected to the exterior of the shell at the top and bottom, are castings 8 and 9. These castings are each provided with a semi-circular channel l0, and a straight channel 11. Connected to the forward end of the semi-circular channel, in casting 8 is a steam entrance pipe 12, controlled by valve 13, and steam exhaust pipe 14: controlled by valve 15 is connected to casting 9. It will be seen that th valves 13 and 15 are readily accessible to control the passage of steam through the coils in the interior of the shell.

Situated within the shell, are manifolds 16-17, between which are interposed the two sets of coils 1819. At one end (rear) of each manifold, there is provided an extension 20, the extreme end 21 of Which is solid and provided with a screw thread 22. The manifolds are also each provided with plates 23, which, when the manifolds are in position, bear against/the inside of the shell 5. 0n the end of the extension 20, and eooperating with the screw thread 22, are nuts 24:. The manifolds 16l7 are carried by a roller -25, which bears upon the upper edge of the bracket 26. 27 represents an eye which is connected to, the upper manifold 16, and

which is adapted to cobperate with a pivoted lever 28 on the outside of the shell 5, through a hook 29. 30 represents the door of the evaporator, secured in the usual manner to the shell, and adapted to be swung away from the shell through the lever 31 and link 32, mounted on the outside of the shell opposite to the lever 28. 33 indicates openings in the extensions of the manifolds 16-17, by reason of which the manifolds are brought in connection with the channels 10 of the castings 8 and 9.

In Fig. 3, the parts are shown in the operative position, with the shell closed. When in this position, the extensions 20 of the manifolds l617 are in the channels 11 of the castings 8 and 9, and are secured in position by the nuts 24. Fig. 4 shows the parts in the open position, with the door swung out and the manifolds and coils half way out of the shell. When the manifolds and coils are in the position shown in dotted lines, they are in a position to have the salt upon them, removed, when they can be swung back into position in the shell, or a new set of coils and manifolds may be substituted for those removed. To remove the manifolds and coils from the shell, they are first slid forward, that is, to the left of Fig. 4, the roller 25 moving over the upper edge of the bracket 26, until the parts reach the position shown in Fig. 4, at which time the lever 28 is swung inward and. the hook 29 connected with the eye 27 on the upper manifold. When this connection is made, the manifolds and coils may be carried forward, being sup- Having thus described my invention, what I claim is: v

1. In an evaporator, the combination of an inclosing shell, steam connections attached permanently to the shell, upper and lower manifolds projecting into the shell, each of such manifolds provided with a projecting member adapted to enter and cooperate with the steam connection near which it is placed, means for detachably securing the manifolds to the steam connections and steam coils interposed between the manifolds.

2. In an evaporator, the combination of an inclosing shell, steam connections attached permanently to the shell, upper and lower manifolds projecting into the shell, steam coils interposed between the manifolds, each of such manifolds provided with a projecting member adapted to enter and cooperate with the steam connections near which it is placed, means for detachably securing the manifolds to the steam connections, and means not connectedto the manifolds and steam coils but adapted to move such parts, when desired, wholly out of the inclosing shell.

3. In an evaporator, the combination of an inclosing shell, a removable-door, steam con nections attached permanently to the shell and opposite to the door, upper and lower manifolds projecting into the shell, each of said manifolds provided with a projecting member adapted to enter and cooperate with the steam connection near which it is placed, steam coils interposed between the manifolds, and means for detachably connecting the manifolds to the steam connections and steam coils.

4. In an evaporator, the combination of an inclosing shell, a removable door, steam connections attached permanently to the shell and opposite to the door, upper and lower manifolds projecting into the shell, each of said manifolds provided with a projecting member adapted to enter and cooperate with the steam connection near which it is placed, steam coils interposed between the manifolds, means arranged external to the shell for supporting the door when separated from the shell, means within the shell for supporting the manifolds and coils when in the shell, means'arr angcd external to the shell for supporting the manifolds and coils when exterior to the shell, and means for detachably securing the manifolds to the steam connections.

In testimony whereof, I aflix my signature, in presence of two wltnesses.
